前記第１および第２ワンウエーベアリング７１、７２は、図９および図１０に示すように、前記延長管部２７と回転軸３０の外周面にそれぞれ結合固定される内輪７３と、前記内輪７３の外側に回転可能に結合され、前記連動軸６０の内周面に結合固定される外輪７４と、前記内輪７３と外輪７４との間に備えられ、内輪７３の回転方向に応じて前記内輪７３と外輪７４を選択的に固定する固定キー７５とで構成され、前記内輪７３が時計回りに回転する場合にだけ、前記外輪７４が時計回りに回転するように構成される。 As shown in FIGS. 9 and 10, the first and second one-way bearings 71 and 72 have an inner ring 73 coupled and fixed to the outer peripheral surface of the extension pipe portion 27 and the rotary shaft 30, respectively, and the outer side of the inner ring 73. An outer ring 74 that is rotatably coupled to and fixed to the inner peripheral surface of the interlocking shaft 60, is provided between the inner ring 73 and the outer ring 74, and the inner ring 73 and the outer ring are provided according to the rotation direction of the inner ring 73. It is composed of a fixed key 75 that selectively fixes the 74, and the outer ring 74 is configured to rotate clockwise only when the inner ring 73 rotates clockwise.

このために、前記外輪７４の内周面には、反時計回りに行くほど凹となる傾斜溝７４ａが形成され、前記固定キー７５は、側方向に延長された円棒形状で構成されて前記傾斜溝７３ａの内部に挿入されるように設置される。 For this purpose, an inclined groove 74a that becomes concave as it goes counterclockwise is formed on the inner peripheral surface of the outer ring 74, and the fixing key 75 is formed in a circular bar shape extending in the lateral direction. It is installed so as to be inserted inside the inclined groove 73a.

したがって、前記内輪７３が反時計回りに回転する場合、前記固定キー７５は、傾斜溝７４ａの深い所に移動して内輪７３と外輪７４の結合を解除し、これに応じて、内輪７３が空回転されるようにする。 Therefore, when the inner ring 73 rotates counterclockwise, the fixed key 75 moves to a deep part of the inclined groove 74a to release the coupling between the inner ring 73 and the outer ring 74, and the inner ring 73 is emptied accordingly. Make it rotate.

反対に、前記内輪７３が時計回りに回転する場合、前記固定キー７５は、傾斜溝７４ａの低い所に移動して内輪７３と外輪７４との間に挟まれ、これに応じて、内輪７３と外輪７４がともに時計回りに回転されるようにする。 On the contrary, when the inner ring 73 rotates clockwise, the fixed key 75 moves to a lower part of the inclined groove 74a and is sandwiched between the inner ring 73 and the outer ring 74, and accordingly, the inner ring 73 and the fixed key 75. Both outer rings 74 are rotated clockwise.

これらのワンウエーベアリングは、一般的に使用されるものであるため、これについての詳細な説明は省略する。 Since these one-way bearings are generally used, detailed description thereof will be omitted.

前記変速ギア８０は、図８に示すように、前記第２ねじ山６１に噛合う第３ギヤ部８１と、前記第３ギア部８１に比べて直径が大きく構成され、前記第３ねじ山９１に噛合う第４ギヤ部８２とで構成され、前記連動軸６０の回転速度を増速させて前記出力ギヤ９０に伝達するように構成される。 As shown in FIG. 8, the speed change gear 80 has a third gear portion 81 that meshes with the second thread 61 and a diameter larger than that of the third gear portion 81, and the third screw thread 91 is configured. It is composed of a fourth gear portion 82 that meshes with the above, and is configured to increase the rotational speed of the interlocking shaft 60 and transmit it to the output gear 90.

前記駆動スプロケット１００は、周り部に結合されたチェーン８を介して自転車の後輪に備えられた従動スプロケット７に連結される。 The drive sprocket 100 is connected to a driven sprocket 7 provided on the rear wheel of the bicycle via a chain 8 coupled to a peripheral portion.

したがって、前記駆動スプロケット１００が時計回りに回転すると、自転車の後輪が時計回りに回転して自転車が前進することになる。 Therefore, when the drive sprocket 100 rotates clockwise, the rear wheel of the bicycle rotates clockwise and the bicycle moves forward.

前記クラッチ機構１０１は、前記支持筒体１０の外側に位置するように前記出力ギヤ９０の延長部９２に備えられたものであって、使用者が図示されていない調節手段を操作すると、前記出力ギヤ９０と前記駆動スプロケット１００を相互に連結するか、または連結を遮断するように構成される。 The clutch mechanism 101 is provided on the extension portion 92 of the output gear 90 so as to be located outside the support cylinder 10, and when the user operates an adjustment means (not shown), the output The gear 90 and the drive sprocket 100 are configured to connect to each other or break the connection.

これらのクラッチ機構１０１は、様々な種類のものが開発されて使用されるため、これについての詳細な説明は省略する。 Since various types of these clutch mechanisms 101 have been developed and used, detailed description thereof will be omitted.

前記左右側クランクアーム１１１、１１２は、前記回転筒体２０の延長部２１と回転軸３０の端部に前方に延長されるように備えられ、使用者が前記左右側ペダル１１３、１１４を交互に下側に踏み、左右側クランクアーム１１１、１１２と回転筒体２０と回転軸３０を交互に時計回りに回転させ得るように構成される。 The left and right crank arms 111 and 112 are provided so as to extend forward to the extension 21 of the rotary cylinder 20 and the end of the rotary shaft 30, and the user alternately shifts the left and right pedals 113 and 114. It is configured so that the left and right crank arms 111 and 112, the rotary cylinder 20 and the rotary shaft 30 can be alternately rotated clockwise by stepping on the lower side.

これらの自転車駆動装置の作用を図面に基づいて説明すると、次のようである。 The operation of these bicycle drive devices will be described as follows based on the drawings.

このとき、図面で実線の矢印で表示された部分は、時計回りに回転される部分を示し、点線の矢印で表示された部分は、反時計回りに回転される部分を示す。 At this time, the portion indicated by the solid arrow in the drawing indicates the portion rotated clockwise, and the portion indicated by the dotted arrow indicates the portion rotated counterclockwise.

まず、図３に示すように、前記左側クランクアーム１１１が下側に回動し、右側クランクアーム１１２が上側に回動した状態で使用者が図１１に示すように、右側ペダル１１４を下側に踏んで右側クランクアーム１１２を時計回りに回転させると、前記回転軸３０が時計回りに回転されながら回転軸３０の駆動力が前記第２ワンウエーベアリング７２を介して前記連動軸６０に伝達されて連動軸６０を時計回りに回転させ、これによって、前記変速ギア８０が反時計回りに回転されて前記出力ギヤ９０を時計回りに回転させることにより、前記駆動スプロケット１００を時計回りに回転させる。 First, as shown in FIG. 3, in a state where the left crank arm 111 is rotated downward and the right crank arm 112 is rotated upward, the user sets the right pedal 114 downward as shown in FIG. When the right crank arm 112 is rotated clockwise, the driving force of the rotating shaft 30 is transmitted to the interlocking shaft 60 via the second one-way bearing 72 while the rotating shaft 30 is rotated clockwise. The interlocking shaft 60 is rotated clockwise, whereby the transmission gear 80 is rotated counterclockwise and the output gear 90 is rotated clockwise, thereby rotating the drive sprocket 100 clockwise.

これと共に、前記回転軸３０が時計回りに回転されることによって、前記サンギア５０が時計回りに回転されるとともに、前記プラネットギア４０を反時計回りに回転させ、これによって、前記回転筒体２０と左側クランクアーム１１１が反時計回りに、すなわち、上側に回動する。 At the same time, the rotating shaft 30 is rotated clockwise, so that the sun gear 50 is rotated clockwise and the planet gear 40 is rotated counterclockwise, whereby the rotating cylinder 20 and the rotating cylinder 20 are rotated. The left crank arm 111 rotates counterclockwise, that is, upward.

そして、前記左側クランクアーム１１１が上側に回動し、右側クランクアーム１１２が下側に回動した状態で、使用者が図１２に示すように、左側ペダル１１３を下側に踏んで左側クランクアーム１１１を時計回りに回転させると、前記回転筒体２０が時計回りに回転されながら回転筒体２０の駆動力が前記第１ワンウエーベアリング７１を介して前記連動軸６０に伝達されて連動軸６０を時計回りに回転させ、これによって、前記変速ギア８０が反時計回りに回転されて前記出力ギヤ９０を時計回りに回転させることにより、前記駆動スプロケット１００を時計回りに回転させる。 Then, with the left crank arm 111 rotated upward and the right crank arm 112 rotated downward, the user steps on the left pedal 113 downward as shown in FIG. 12, and the left crank arm. When the 111 is rotated clockwise, the driving force of the rotating cylinder 20 is transmitted to the interlocking shaft 60 via the first one-way bearing 71 while the rotating cylinder 20 is rotated clockwise, and the interlocking shaft 60 is moved. Rotating clockwise, thereby rotating the speed change gear 80 counterclockwise and rotating the output gear 90 clockwise, thereby rotating the drive sprocket 100 clockwise.

これと共に、前記回転筒体２０が時計回りに回転されることによって、前記プラネットギア４０が時計回りに回転されるとともに、前記サンギア５０を反時計回りに回転させ、これによって、前記回転軸３０と右側クランクアーム１１２が反時計回りに、すなわち、上側に回動する。 At the same time, the rotary cylinder 20 is rotated clockwise, so that the planet gear 40 is rotated clockwise and the sun gear 50 is rotated counterclockwise, whereby the rotating shaft 30 and the rotating shaft 30 are rotated. The right crank arm 112 rotates counterclockwise, that is, upward.

すなわち、使用者が左側ペダル１１３を下側に踏むと、右側ペダル１１４は上昇するとともに、駆動スプロケット１００は時計回りに回転され、使用者が右側ペダル１１４を下側に踏むと、左側ペダル１１３は上昇するとともに、駆動スプロケット１００は時計回りに回転される。 That is, when the user steps on the left pedal 113 downward, the right pedal 114 rises, the drive sprocket 100 is rotated clockwise, and when the user steps on the right pedal 114 downward, the left pedal 113 rises. As it rises, the drive sprocket 100 is rotated clockwise.

したがって、使用者が左側ペダル１１３と右側ペダル１１４を交互に下側に踏むと、前記駆動スプロケット１００が持続的に時計回りに回転されて自転車を前進させる。 Therefore, when the user alternately steps on the left side pedal 113 and the right side pedal 114 downward, the drive sprocket 100 is continuously rotated clockwise to advance the bicycle.

このように構成された自転車駆動手段は、使用者が左側ペダル１１３と右側ペダル１１４を繰り返して下側に踏むことにより、３６０度ではない約１２０度の回転だけで自転車を前進させ得るため、左側ペダル１１３と右側ペダル１１４を回転させなければならない従来の自転車駆動手段に比べて使用がより便利であるという利点がある。 The bicycle driving means configured in this way allows the user to repeatedly step on the left side pedal 113 and the right side pedal 114 to move the bicycle forward by rotating the bicycle by about 120 degrees instead of 360 degrees. It has the advantage of being more convenient to use than conventional bicycle driving means that must rotate the pedal 113 and the right pedal 114.

特に、一般的な自転車の場合、右側クランクアームと駆動スプロケットが一体化しているが、本発明の場合、駆動スプロケット１００と右側クランクアーム１１２がそれぞれ別に分離され、それぞれ別の駆動が可能となる特徴がある。 In particular, in the case of a general bicycle, the right crank arm and the drive sprocket are integrated, but in the case of the present invention, the drive sprocket 100 and the right crank arm 112 are separated from each other so that they can be driven separately. There is.

発明の実施のための形態は、前記の発明の実施のための最善の形態で一緒に記述された。 The embodiments for carrying out the invention are described together in the best embodiment for carrying out the invention described above.

本発明は、自転車駆動装置に関するものであって、自転車に適用可能であり、繰り返し可能性があるため、産業上の利用可能性がある。 The present invention relates to a bicycle drive, is applicable to a bicycle, has repeatability, and has industrial applicability.
